Subject: [PATCH v3 10/13] arm64: dts: mediatek: mt7988a-bpi-r4: add gpio leds

From: Frank Wunderlich <frank-w@...lic-files.de>

Bananapi R4 has a green and a blue led which can be switched by gpio.
Green led is for running state so default on.

Green led also shares pin with eeprom writeprotect where led off allows
writing to eeprom.
